Environmental Friendliness: High utilization rate of powder coating with minimal solvent emissions, reducing environmental impact and production costs.
-
Diverse Options: Offers a variety of powder coating colors and textures to meet different customer requirements.
3. Process Flow
The process flow of the automatic electrostatic powder coating production line typically includes the following main steps:
| No. | Process Name | Process Description |
|---|---|---|
| 1 | Pre-treatment | Includes degreasing, rust removal, and phosphating to clean the workpiece surface and enhance coating adhesion. |
| 2 | Powder Coating | Uses electrostatic spray guns to evenly apply powder coating onto the workpiece surface. The powder adheres firmly through electrostatic attraction. |
| 3 | Curing Treatment | The coated workpiece is placed into a curing oven, where the powder coating is melted, leveled, and cured through heating to form a hard protective layer. |
| 4 | Inspection and Repair | Checks the coated workpiece for defects such as uneven coating or scratches, and carries out necessary repairs. |
| 5 | Packaging and Storage | Qualified products are packaged and then stored in the warehouse. |
